Hi folks,
below I've posted one of the hardest puzzles I've ever seen originally posted
by Mike Allan who sadly passed away a few years ago. As its such a tough puzzle
to crack I'll give you a big clue, That is that there is something rather
mechanical/clockwork about the solution to the puzzle!
Best wishes,
Mark.

Chess Puzzle
in algebraic notation.
white: Rh4, Kb4, Qc3, Bb3, Nd3, B e3, Nf3, Pg4, Pb6, Pc7.
Black: Ka8, Pb7, Rf4+.
white to win by checkmating black, in an unspecified number of moves.
right now, black's rook on f4 is checking white's king on b4.
good luck.
